I have ubuntu, and I'm trying to chat like I normally do on deviantart, with more than one chat open at once. However, I cannot use tab normally (the tab button makes the cursor vanish rather than helping me type people's usernames), and every time I hit enter, the page refreshes. What am I doing wrong, or how on earth can I fix this? I need to do both of those things without constant refreshing in order to function in the dA chats properly.
